4012.90 - Other:

HTS code 4012.90, categorized under "Other" within the broader heading for retreaded or used pneumatic tires and other rubber tire articles, encompasses rubber items related to tires that do not fit into the more specific subcategories of this heading. This includes items such as tire flaps, which are protective coverings placed inside a tire to prevent wear or damage to the inner tube, and solid or cushion tires that are not pneumatic. The key characteristic is that these are made of rubber and serve a function in conjunction with or as an alternative to traditional tires.

This category serves as a residual for tire-related rubber articles. It is distinguished from its siblings, "Retreaded tires" and "Used pneumatic tires," by its exclusion of complete, albeit used or retreaded, pneumatic tire structures. While those categories focus on the entire pneumatic tire, 4012.90 is for components or alternative tire designs made of rubber.

The subcategories within 4012.90 further refine the classification. "Solid or cushion tires" specifically addresses non-pneumatic tire types designed for certain vehicles where puncture resistance or specific load-bearing capabilities are paramount. The remaining "Other" within 4012.90 will capture any remaining rubber articles pertaining to tires that do not meet the criteria for retreaded, used pneumatic, or solid/cushion tires, such as tire flaps.
